SUZUKI 140 BTL

Suzuki's new outboard engine, the DF140B, features enhancements that further improve its overall performance. The compression ratio has increased to 10.6/1, allowing this over 2-liter outboard engine to increase its top speed and achieve better acceleration while optimizing thermal efficiency.

Energy efficiency has also been improved compared to the well-known DF140A model. Tests have shown a 5 to 6% improvement in fuel consumption for the DF140B over a range of medium to high speeds.

The new cowling incorporates a special air intake optimizing water separation while reducing intake air temperature, enabling higher power delivery at mid-range RPMs. A resonator system further reduces engine noise at all speeds.

The new direct ignition reduces the number of parts and wiring, improving spark generation and combustion efficiency.

The main difference compared to its "little brother" DF115B is that it develops its power over a higher RPM range.
